Lab objectives and outcomes

Students will be able to describe how manipulating the slope and y-intercept values influences the visual representation of a straight line on a Cartesian graph.
Students will be able to construct a linear graph with a specified slope and y-intercept by adjusting the interactive parameters within the simulation.
Students will be able to differentiate the specific impact of changing the slope versus changing the y-intercept on the position and orientation of a line.

Track learner progress

Run this simulation with a class and watch it happen: who started, who finished, and how long each learner took. Drill into a run to see what they actually did.

Group sessions

SimGenie acts as a built-in lab assistant. A learner who gets stuck can ask for a hint by voice, and it adapts its guidance to what they are doing in the scene.
